Vanillin was used to synthesize cationic monomers from the amine group with a tertiary amine. It has both an amine and an aldehyde group. For that, it helps graft to form Schiff base with amino acid-like tryptophan. It is abbreviated by {2-[(diethylamino) methyl]-4-formyl-6-methoxyphenyl acrylate} DEAMVA and evaluated by, e.g., 1H NMR, 13C NMR, and FT IR results were compared with the chemical structure elevated good agreement. 10 and 25 mol % of vanillin monomer was copolymerized with (S). The copolymers of poly (S-co-DEAMVA) were investigated by 1H NMR, FTIR, GPC, and DSC. The grafting with tryptophan has also been modified and exposed to the same investigation methods; further, UV/Vis spectroscopy has designated the pH responsiveness. The study aims to improve the general characterization of polystyrene and produce functional pH-responsive polymer for graft biological molecules in the future.
